A 100 kVA transformer has 400 turns on the primary and 80 turns on the secondary. The primary and secondary resistances are 0.3 and 0.1 respectively and the corresponding reactances are 1.1 8 and 0.035 2 respectively. The supply voltage is 2200 V. Calculate the voltage regulation and secondary terminal voltage for full-load having a power factor of (1) 0.8 lagging and (il) 0.8 leading.
